Jiangnan can't keep people, they always have to leave.
There are lovers but they can't get married in the end.
"It's April in the south of the Yangtze River. Luochuan, the begonia flowers are blooming. I miss you very much."
"It's April in the capital. The moon is full and the begonia flowers are blooming. I miss you very much."
Intention: Lovers cannot get married eventually
